290
Because 2*100= 200
and 9 is 9 more than 0
Percent literally means per one-hundred so:
365(p/100)=146 multiply both sides by 100
365p=14600 divide both sides by 365
p=40%
Given:
μ = 55 in, population mean
σ = 6 in, population standard deviation
Part (a)
x = 48 in, the random variable
Calculate the z-score.
z = (x - μ)/σ
= (48 - 55)/6
= -1.667
From standard table, obtain
P(X < 48) = 0.12167
Answer: 0.1217 (tyo 4 dec.places)
The first step to solve this problem is to find 10% of 3,500. To do this you would set up the equation x/3,500=10/100. You then multiply 3,500 by 10, getting 35,000, then divide that by 100. The 10% would then be 350. Finally, you would subtract 350 from 3,500, getting 3,150 as your final answer.
Answer:
Step-by-step explanation:
moments about the fulcrum should be equal
IF x is the distance of the fulcrum from the 90 lb child
90[x] = 60[12 - x]
90x = 720 - 60x
150x = 720
x = 4.8 ft
90(4.8) = 432 ft•lb
60(12 - 4.8) = 432 ft•lb
